Any state agency or political subdivision may directly sell or exchange real property to which it holds title with the School Land Board for the benefit of the permanent school fund if the sale or exchange is for market value. § 272.001, Local Government Code, does not apply to an exchange under this section. A political subdivision must provide the governor with advance notice of a proposed sale or exchange under this section, which notice must be sent to the governor at least 30 days before the transaction may be effected. In addition, the governor may disapprove any sale or exchange of real property by a state agency under this section prior to the sale or exchange. The state agency contemplating a sale or exchange under this section shall submit to the governor a formal request for approval. The state agency may conduct the sale or exchange unless the governor gives the state agency written notice disapproving the sale or exchange. The governor must provide written notice of disapproval under this section not later than the 30th day after the date the governor receives the written request for approval.
